clang-19: error: unknown argument: '-EHsc'
```

I presume the `-EHsc` option is vital for the test here, and I guess it's not folded into `%clang_cl_asan`. See 3c1aa20c63548c77ddce3dabc7b25c7c7edccaac and https://github.com/llvm/llvm-project/blob/llvmorg-19-init/compiler-rt/test/asan/lit.cfg.py#L148-L199 for how options that differ are folded into lit substitutions, so the tests keep working on both MinGW and clang-cl style setups.

Not sure how relevant this test is for MinGW style setups though. If nothing else, I'll probably push an added `// UNSUPPORTED: target={{.*-windows-gnu}}` to this test, to unbreak my test setups. Otherwise we could abstract this option behind a substitution like the existing ones.
